So I've completed my LMOS 3 gun build and I want even more!!! I'm selling my JP LMOS BC and going with a whiskey arms LBC to even further decrease recoil. I'm also anal and don't want to ruin my Battle arms LW upper billet receiver... So I'm gonna mad black (better than but similar to micro slick) the whiskey arms Bolt carrier and inside of the upper receiver to prevent wear from aluminum to aluminum contact as well as even more lubrication properties. What do you guys think? And yes I'm running an adj. gas block, white spring JP SCS, and JP tacticle brake. It's also super cheap at 105 bucks! Here's a link to the coating

A couple of thoughts...
First, compare carrier weights. A J.P. LMOS is already DAMN LIGHT!
Second, if you are going to run an aluminum carrier I would consider using the Hydra Fire cam pin to reduce wear, in addition I would consider using the New Frontier Armory polymer hammer to eliminate the chatter that occurs on the underside of an aluminum carrier from the steel hammer.
There is a member here working diligently on an aluminum carrier that he's hoping will go 10,000 rounds. He's several permiations in, and I have to state he's making outstanding progress. I'm not at liberty to say anything more, but defiantly a better aluminum carrier is in the works.
